These questions weren't answered in your earlier reply.

Though if only home= is supported by static, then it seems there isn't a 
mechanism to specify the mailbox type (other than as implied by the 
trailing slash) or the INBOX location.

It seems a little confusing that in a real account scenario home= 
defines the user's actual home directory (right?), but not necessarily 
their mail directory, yet under a virtual user scenario the two are the 
same thing. Or maybe it just seems that way because my default_mail_env 
is set to the identical path in my case, as would be typical in a 
virtual user setup.


Also, would it be practical to check during startup that the UID and GID 
specified by the static db don't fall outside the range of:

first_valid_uid = 1000
last_valid_uid = 5001
first_valid_gid = 1000
last_valid_gid = 5001

I initially had that problem with my setup, but fairly quickly saw a run 
time error in the log that led me to the cause.
